For the upcoming Legends Cup Tournament (open to everyone), the format will be this [which is subject to change]:
Your team will not be able to exceed 7 points:
2 Points-Ancient, 1.5 Points Legendary, 1 Point Emissary/Zenith, .5 Points Superior, 0 Points Regular

It will be Round Robin with elimination. After you have played against your entire bracket, the top player(s) will be able to proceed in the tournament.
